Two questions:
Which BA fare classes can I use AsiaMiles to upgrade?
If I upgrade a BA flight using AsiaMiles, can I credit the miles earned from the flight to AA?
Thank you very much for your help.
Sincerely,

You can but it would involve a lot of letter writing. As CX books upgrades in their award codes like a free ticket, AA's computer will reject it as a paid ticket, hence you must write in and show to AA that the MCO that CX issued you is for an award upgrade and that you are to be credited for the miles from the ticket purchased.
